Hebei GN Solids Control Co., Ltd is a top manufacturer of solids control equipment and system for oil and gas drilling.
In a complete set of solids control system, there are 4 stages of treating equipment-shale shaker, desander, desilter,
and decanter centrifuge. Today, We’ll talk about the second and third stage treatment of desander and desilter cyclones.
The desander can separate solids over 40 microns,and the desilter can separate solids over 20 microns.

GN Hydrocyclone

 

Normally a desander cyclone includes shell with mud inlet port and liquid outlet port on it, cone body, drop in Apex
and orifice nut which can adjust the opening of the drop in Apex; a desilter cyclone includes shell with mud inlet port
and liquids outlet port on it, connecting cone tube drop in Apex and orifice nut, and also elbow connecting the cyclone
to the liquids discharge pipeline. When working, the mud will be inject to the cyclone in a tangent line direction by a
feeding pump with the certain pressure, then mud will do rotary movement. The lighter liquids will move forward and then
flow out through the liquids discharge pipeline; the heavier solids will move downward and
sprayed out through the drop in Apex.

Generally, cyclones can be assembled into 3 kinds. The first one is desander cyclone alone or combined with a underflow
shale shaker; the second one is desilter cyclone alone or combined with a underflow shale shaker; the combination with
desander and desilter cyclones and underflow shale shaker. The third one with compact footprint can save much space.
And the underflow shale shaker is used to drying the solids discharged from the cyclones to recollect more useful liquids.
After that,the liquids will be delivered into decanter centrifuge for further treatment.
